If you are changing BB anyway, then you could just get a BB that is a little longer than recommended for the triple. And eat the slight increase in Q factor, of course.
If the triple chainset requires an assymetric BB then this is a little more tricky.
I need easier gears on a budget.
I'm currently running a 12-36 cassette, slx m662 9 speed rear mech and a 33t chainring on a double.
Thinking of switching to a 26 or 28t up front on a triple run as a 1x
Will this work ok? Chainline will be off so I guess the chain will wear quicker?
It's on long tail cargo bike so only using it for bezzing around town.
